About Datavant
The data collaboration platform trusted for healthcare.
Datavant operates the largest connector of identified and de-identified health data in the world, turning fragmented data into intelligence that drives action and impact for our customers.


Driving connectivity into action
Datavant provides the foundational infrastructure linking the healthcare ecosystem.
Our network powers secure, compliant data exchange across the industry’s most complex environments.
We connect payers, providers, life sciences, legal and insurance organizations, government agencies, and real-world data partners.
We locate patients, facilities, and records with industry-leading accuracy–ensuring reliable data movement at scale through advanced connectivity engineering.
The result is speed, cleaner data, and a unified network that unlocks new, AI-driven use cases.
It’s hard to be in the trenches, especially for a company that’s building core infrastructure. But through the challenge, I hope everybody recognizes the impact that data logistics is having and will have, because it is truly transformative.

Datavant listens to their customers and customizes their services based on our priorities and needs. This is what makes them unique.

…It was a unique ask to take a new EMR live while also finding a ROI solution for both future and legacy EMRs in parallel… Datavant has been an excellent partner that has only exceeded expectations. I am thankful we chose them as our ROI Solution.
